Our team is continuously working on making Chartoasis.com's chart software better so the software is updated regularly. The Java environment always checks if there is a newer version of the chart software on the server of Chartoasis.com and downloads that one. If despite Java's automatic update you experience that a just announced feature is missing from the chart software you run on your local computer do the following:

Click the Java icon in Control panel (either Start menu/Control panel or Start menu / Settings / Control panel - if you are in "Category view", change to "Classic view"). Click the Settings button in the "Temporary Internet files" section (in the bottom).

If above step does not solve the problem removing all Java applets and other applications from the temporary storage (cache) may be the solution. Click "Delete files" and check and check "Applications and applets" if possible, then click OK. This will delete all Java applications and applets from the cache. Later these will always be donwloaded before using them ensuring that always the latest version is used. Restarting the browser may be needed after this step as well.
